IMPRO'AVENIENT IN S'U'LKY CORN-PLANVTBRAND PLOW COMBINED.

' lhe Schedule referred t'o in these Letters Patent and making part of the same.

To all whom it/mag/ concern:

Be it known that we, `Rnzls RoBlNs and ALBERT S. ROBINS, both of Dundas, in the ,county of Richland, and State of Illinois, have invented a new and useful Improvement in Combined Corn-Planters and Ilowers; and we do hereby declare the following to be a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, which are made a part of this specification.

Our invention relates to that class of combined planters and plowers, or cultivators, termed sulkies andu consists in certain novel constructions, combinations, and larrangements of parts hereinafter specified. l

The machine, in its complete form, furrows,.plants, and covers, and is adapted, by the removal or locking of the planting-devices, and a novel adjustment of the nachiue, to be employed for plowing or cultivating the p ants.

The planting-device is adapted to be operated automatically by the movement of the machine, or by the feet ofthe driver, or be locked from movement by either, when it is not desired to plant.

The plows or shovels are adapted to be elevated separately or simultaneously, and to be held in an elevated position, as in turning and going to and from the field. y

The inner shovels arevalso adapted'tb be adjusted laterally to dodge the 'plants in plowing.

The coveling-rollersalso are adapted to be elevated when desired.

The various adjustments of the planting, covering, and plowing-devices, are adapted to be made from the driveiis seat in the most convenient manner.

In the drawings- Figure 1 represents a plan -view ot' our improved, machine, partly in horizontal section, and with portions oi' the tongue and axle, with one of the wheels broken y away.

Figure 2 is a longitudinal section of the machine on the line a: x, fig. l.

Figure 3 is a rear elevation of the machine, with certain parts removed and others in vertical section on -the line y y, fig.i1.

Figure 4 is a sectional perspective view, on an enlarged scale, of a portion ofthe axle and its' adjuucts, representing the provision for adapting the machine forv planting or plowing.

Figure 5 is a sectional end v-iew, on about'the samev yD represents a tongue ordranght-pole gained into the frame A, so as to form a part thereof, and' attached separately to the axle B by a vertical bolt, a', and also Ito the front end of the frame A by a4 bolt, a".

E represents a driverfs seat, which is mounted at tlie rear end of the frameAon a spring, F, in the usual manner. y p

G G represent a pair of 'seed-boxes or hoppers, ot'

suitable capacity, and any desired form, andsupported on the frame A immediately behind the axle B, as shown, or -in other convenient position, through the `medium of a base or bottom H.

This Abase is provided, under cach lseed-box, with vertical perfor-ations h h h', as represented in iigs. 1 and 3, and isalso'perforated longitudinally, transversely of the machine, as shown in figs. 2 and 3, for the reception of a dropping-slide, I, provided with a single perforation, t', under each feed-box, which, by the rcciprocation of said slide, are made to' communicate alternately with one of the holes h, andthe hole h in the bottoms of the seed-boxes, thus dropping once for each movement.

p The slide I is 4covered with a thin plate, I' preferably of metal, perforated similarly thereto, and which. being made adiustablc'by the provision of a number of perforations t'* for the reception of its attaching-pin di, as represented in iig. 3,' serves to regulate the number ot' grains dropped, as desired.

Said slide -is also providedoat one end with a depending arm, i', through which itis engaged by a spring, K, having a tendency to hold it in the position represented, and at its opposite cud with a fricf tion-rollend", mounted in a detachable cap, i, and

which forms the bearing-surface for a crown-cam, L,

by the rotation of which, in connection with said spring K, a constant reciprocating movement is imparted to said slide.

The cam L is mounted loosely on the extended hub c of the wheel O', and may be constructed as represented, by the attachment of' a suitably bent wire to the face of a wooden disk, or in any other suitable manner. ,Y

It is connected-with the wheel G', inthe forward movement of the machine, by the engagement ot" a spring pawl, l, attached thereto, with al ratchet-disk, c, attached to the face of thc hub c', said connection preventing the motion of the wheel being imparted to it in any backward movement oi' the machine. p

The dropping-slide I is further provided with afriction-roller, i4, arranged ina slot therein between the seed-boxes, for th engagement of the end nl, of a bent bell-crank lever, M, fulcrumed at m* in a standard N on the bed-piece of the seedboxesand connected by a chain, M', to a. lever or treadle, M, fulcrumcd at m in the frame A, and adapted to' be operated by the feet of the driver, to reciprocate said slide -independent of the motion of the cam L, or by its depression to hold said slide from movement, it beingl adapted to be held in that position by the engagement of a bearing-plate, m, thereon with a catch, fn, on the face of the standard N. K

When the slide I is operated by foot7 through the 'devices last described, its friction-rollert for the en-4 gagement of the cam L isremoved, and its end covered by athimble, fi, iig. 6, to fprotect thensame.

O O,- O O represent two pairs of shovels or plows hinged to the front end of the frame A by stiff and swivel-joints, o o', respectively, the latter pair O being constructed, andboth arranged in the usual manner.

The knees O* of the shovels ov plows O, are constructed as represented in igs. 2, 43, and 5, with iar ing cavities or chambers 0*, into which the seed is discharged from the .slide I,the passage of the seed therethrough being regulated by pivoted valves P, actuated, through connecting-rods P'-, by bent rocklevers P, fulcrumed at p" in brackets 0*', and engaging direct withthe dropping-slide I, in a central slot or slots, fis, therein.

Q Q represent covering-rollers, which are mounted in frames Q', pivoted at q'* to the main i'ame A, and alranged directly behind the planting-shovels or plows yO, as represented in gs. 1 and 3, to close up the furrows over the seed.

They are adapted to be elevated, when desired,

by connection, by meansof a chain, Q, attached to eyes or staples y, on their fi-ame Q, 'to the arms' q of a rock-shaft, Q, hinged at qm* to the baselI of the seed-boxes, and connected in turn by chain or link, Q, attached to a central arm, q, there of, and to an arm, q", of a rock-lever, Q2, also fulcrumcd, at qi* to said base H, and held at its upper end in a loop or bracket, qs, on the side of' the driversseat E, where .it'may be conveniently reached and actuated as desired. The lever Q is held, to retain the rollers in-their elevated position, by engaging with the front edge of the seat E.

The shovels or plows O O' are connected, at a suit- .able point behind their pivots, by vchains It tothe front ends of a corresponding number of levers or treadles It', 'ulcrumed at i" to a cross-bar, A', ofthe frame A, and having their free ends in` convenient positions for the engagement of the drivers feet.

Said shovels or .plows are further connected at the same or other suitable point, by cords, rods, or chains S, to the arms s', of a rock-shaft, S', mounted transversely of thel frame A, in front of the bar A', or in other convenient position, and connected by a chain, S,"attached to one or more of said arms s', or to an additional arm or arms, to the end of a rock-lever, S, fulcrumed at s on the bar A' ot' the frame A, or in other convenient position', its rear end extending to within convenient reach ofthe drivel"sseat.

A catch, s4, on the `upper side of 'the axle B, or at other convenient point, by engagement with said-lever S when in its-depressed position, serves to retain the shovels or plows in an elevated position.

The shovels or plows O are supported laterally, bc-

sides, by the form of their pivots o, as before described,

by {igid depending rods or fingers 0** attached to the front edge of the axle B, or other convenient point lhev shovels or plows O' are provided on their inner sides with staples o'*, for the engagement of the lower ends of two upright rods or levers T, connected at their upper end s by a bar or link, T', and fnlcrltmed at an intermediate p'oint, t, to abar or plate, T*, secured transversely of the tongue D. v

The bar or link T' is provided with a number of l perforations,` t', to admito the lateral adjustment of said rods, and with a central socket, t, for the rel-- ception of the upper end of a lever, T, by which to move said rods.

Said lever is fulcrumed at t on the axle B, or at other convenient point, and is provided at its lower end with pedals or foot-rests t* for the engagement ofthe drivel-s feet, andalso, if desired, above the bar T', with a'handlve, 15, for the engagement of the hand ofthe driver. It is held lin its normal position byengaging with a central notch, ti, in a bracket, T, projecting upward iom the axle B.

The object of these devices is to adapt the inner plows, which straddle the rowto be dodged,.so as to escape plants which may be out oi' line, or be held in a normal position, as desired, and also to adjust said plows to suit the row.

By the described arrangement the shovels are adapted tov be controlledby either the feet or hand of the driver, as may be lnost convenient, and also to be expeditiously and permanently7 adjusted toany de` sired dist-ance apart, and locked in a central position, asdesired. v v

- In changing the use of themachine from plowing to cultivating, and cica versa, it is desirable to vary the width ot' the machine. To accomplish this, the' axle B is divided, as represented in tig. 4, at the point where the tongue D is attached to it, and the adjoin-y ing faces of the two parts are provided with a number of vertical' grooves, b, forming, when brought together, as represented, sockets for the reception of the bolt a', by which said attachmentl is made. Y

By the adjustment of the two parts past each other, several successive holes or sockets are formed by the registering or uniting of different grooves in the faces of the two parts ot' the axle.

vBy the insertionof the bolt, at the .same point,

through one or the other of these holes or sockets, the' length of the axle is determined.

The axle at this pointl rests in a guide or supporting-plate, U, supported on the tongue D, and is covered by a corresponding pl'ate, V, through both of which also the bolt a passes.

The devices for elevating the shovels or p1ows,- and the covering-rollers, 'are omitted in iig. 3

Instead of the chains specified and represented as connecting the various operating parts of my machine, rods or cords may be substituted where applicable, and

vice versa. y

The precise forms and proportionsnamed and repl resented for the'l various parts may also obviously, iu many instances, be varied without changing the results produced.

The several parts of the machine may be made of any suitable material.
